1. Hit install on Python and accept the defaults.
2. Install a simple text editor with syntax highlighting.
3. Open a file right on your desktop and type two commands in it and press F5 or something to run it.
Anaconda and Jupyter are great tools, but even they add complexity you don't need when teaching absolute beginners how accessible this can be.
Here's Python. It's installed. Tell the computer what you want to do inside a file. You understand text files and how to store them where you want, use your own conventions for that. Shove it in documents or whatever. We'll learn about project management and version control later, when you're writing programs more than 20 lines long.
